Sencha Touch 2.0.1.1 Local Store not storing values

Hi All,
I am trying to store in the local storage and its not getting stored.
I need to store two values as state id and license type as 1 record and next time I will update it. So the store will always has 1 record like below.

Code:

{
'stateId': 'NJ',
'licenseType': 'BDL'
}

I tried for the last 2 days and with different option but its not storing.
Can someone please tell me what can be the problem in my code.

Do you use the developper tool in chrome? (Ctrl-Shift-I)
If not, you really should! Because in the "Resources" tab, you'll find all the Local Storage objects that are currently stored, and many other really helpfull features!
